BSN Rod Seal – Double-Acting Hydraulic Rod Seal

BSN Rod Seal – Double-Acting Hydraulic Rod Seal with Anti-Extrusion Design for Medium to High-Pressure Cylinders.

BSN high-performance rod seal for medium to high-pressure hydraulic cylinders. Double-acting, anti-extrusion, low-friction. PU, –35°C~110°C, ≤40 MPa, ≤2.5 m/s.

BSN Rod Seal – A premium hydraulic rod seal engineered for double-acting cylinder applications requiring reliable bidirectional sealing and extrusion protection. This double-acting rod seal features an asymmetric lip profile that provides positive sealing in both stroke directions under dynamic and static conditions. The anti-extrusion design with reinforced heel section resists pressure-induced deformation and maintains groove stability under cyclic loading. Optimized lip geometry minimizes friction, stick-slip, and heat generation for extended service life. The compact cross-section fits standard groove profiles, making it an ideal sealing solution for medium to high-pressure hydraulic cylinders in mobile and industrial equipment. Material: high-grade abrasion-resistant polyurethane. Temp: –35°C to +110°C. Pressure: up to 40 MPa. Speed: up to 2.5 m/s.
